The above video doesn't show it changing gears... I was wondering how it did it. It is (sort of) covered in the "fully explained" YouTube video: https://www.youtube.com/watch?v=-9gQ1KRhesM

Explanation: very complicated with a battery powered wireless electronic shift mechanism embedded in the drive shaft. The "fully explained" video doesn't show it changing gears either, just explains how they would do it. My take-away is that it doesn't change gears as of the making of the video (July 9, 2018) but "they have a plan..."

Correct in the video you reference, they say "this is how we invision the shifting will occur"
